Smart Grid Standard Published: Key Piece Supporting Modernization of Global Grid



ATLANTA – The smart grid effort underway around the globe will transform the fundamental structure of the grid by combining an intelligence infrastructure with the grid, which will enable two-way flow of both information and electricity.


A key piece needed to support that modernization and transformation is a newly published standard from ASHRAE and the National Electrical Manufacturers Association (NEMA):

ANSI/ASHRAE/NEMA Standard 201-2016, Facility Smart Grid Information Model, provides a common basis for electrical energy consumers to describe, manage and communicate about electrical energy consumptions and forecasts. The standard is packaged with a User’s Manual which will be available soon. Purchasers of the standard will automatically receive a complimentary PDF of the User's Manual upon its release.


Standard 201 defines an abstract, object-oriented information model to enable appliances and control systems in homes, buildings, and industrial facilities to manage electrical loads and generation sources in response to communication with a "smart" electrical grid and to communicate information about those electrical loads to utility and other electrical service providers.



The standard is part of ASHRAE’s supporting efforts for the Smart Grid Interoperability Panel (SGIP), a private-public partnership initiated by the National Institute of Standards and Technology to speed development of interoperability and cyber security standards for a nationwide smart electric power grid.


A “facility” in the context of this standard can be a single family house, a commercial or institutional building, a manufacturing or industrial building or multiple buildings such as a college campus. There is a range of control technology used in these facilities and standards to support them. The Facility Smart Grid Information Model (FSGIM) provides a common framework to guide the development of these control technologies so that they can meet the control needs of a smart grid environment.


The standard provides a way to model real building systems as a combination of four abstract components: loads, generators, meters and energy managers.


The kinds of functionality that will be enabled by the model include:


• On-site generation management

• Demand response

• Electrical storage management

• Peak demand management

• Forward power usage estimation

• Load shedding capability estimation

• End load monitoring (sub-metering)

• Power quality of service monitoring

• Use of historical energy consumption data

• Direct load control


The standard will be supported by a User’s Manual that provides information about how to interpret the features of the model. It also defines a set of anticipated use cases for facility interaction with a smart grid and provides guidance on how to apply the standard to those use cases, according to Bushby. Expected publication of the User’s Manual is early June 2016.


A ballot has been initiated to approve Standard 201 as an International Organization for Standardization (ISO) standard, via ISO/Technical Committee 205 Building Environmental Design. If approved, the ballot, which is expected to take several months to complete, would move the standard to publication as an ISO standard.


Standard 201 builds on and makes use of several other related standards applicable to the smart grid including:


IEEE 61850 (generators)
OASIS WS-calendar
OASIS Energy Market Information Exchange
NAESB REQ Business Practices and Information Models to Support Priority Action Plan 10—Standardized Energy Usage Information (Green Button)
Weather Exchange Model (WXXM)


The cost of ANSI/ASHRAE/NEMA Standard 201-2016, Facility Smart Grid Information Model, packaged with the User’s Manual, is $110, members ($129, non-members). The User’s Manual for Standard 201 will be available soon. Purchasers of the standard will automatically receive a complimentary PDF of the User’s Manual upon its release.
